A kind of bond paper, wherein, comprises titanium white ply of paper, urea-formaldehyde glue layer, modified cyanurotriamide glue-line, and wherein, urea-formaldehyde glue layer is filled in titanium white paper fiber, and modified cyanurotriamide glue-line covers the upper and lower surface of titanium white paper.
A kind of bond paper provided by the present invention and production method thereof, solve the poor problem of existing low quantitative titanium white paper impregnated bond paper covering power, its covering power can with the bond paper of being made by 85g titanium white paper quite, therefore by be coated with titanium dioxide in dipping process, reach the defect of modifying low quantitative titanium white paper, produce high-quality bond paper, greatly reduce production cost.
Detailed description of the invention
The invention provides a kind of bond paper and production method thereof, for making object of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The low quantitative titanium white paper that the embodiment of the present invention adopts is that specification is the titanium white paper of 70g, and its titanium dioxide content is 25-30%.By adding quantitative titanium dioxide slurry to flood 70g titanium white paper, solved the poor problem of low quantitative titanium white paper impregnated bond paper covering power in Lauxite.
The equipment that the present invention adopts is the horizontal double-steeping drying production line of TL1500-2 type, is manufactured by Nantong Tong Lin mechanical & electronic equipment corporation, Ltd.
The principle of the bond paper of being made up of low quantitative titanium white paper is: in dipping process, be coated with titanium dioxide, reach the defect of repairing titanium white paper, thereby produce high-quality titanium white paper impregnated bond paper.
Because the titanium dioxide density of rutile-type is 4.2-4.3g/cm
3if, it is directly added in Lauxite, be easy to disperse bad and conglomeration, thereby with Lauxite layering, therefore must carry out preliminary treatment to titanium dioxide, first make the titanium dioxide slurry of solid content in 50% left and right, then add in Lauxite.
The preparation method of titanium dioxide slurry is: in the water of 500kg, add the alkylphenol polyoxyethylene (OP-10) of sodium phosphate trimer and the 10L of 5kg, stir 5 minutes, then add the titanium dioxide of 500kg, continue to stir 1 hour.In order to ensure good dispersion effect, more than the stirring end line speed of above-mentioned whipping process should be controlled at 1800m/min.
In process of production, Coating Speed is to arrange according to the fugitive constituent of bond paper.In the present embodiment, Coating Speed is set to 12.5 ms/min.
The production method of the bond paper of being made up of low quantitative titanium white paper specifically comprises:
1. the impregnation of urea-formaldehyde glue:
First urea formaldehyde glue is extracted into impregnation bucket and measures, open and stir, add successively bleeding agent, curing agent CT0012, stir and add titanium dioxide slurry after 5 minutes, continue to stir, after 10 minutes, put into glue groove.
Wherein, the addition of titanium dioxide slurry is 4.3% of urea-formaldehyde glue weight.
2. the impregnation of modified cyanurotriamide glue:
Modified cyanurotriamide glue is extracted into impregnation bucket and measures, open and stir.Add successively M306, releasing agent, antitack agent, curing agent CT0235, stir and after 10 minutes, put into upper and lower glue groove.
3. gluing for the first time:
The glue of gluing is for the first time the above-mentioned urea-formaldehyde glue that adds titanium dioxide slurry.Owing to adding titanium dioxide slurry, the permeance property variation of urea-formaldehyde glue, in order to ensure that titanium white body paper has good infiltration, the glue viscosity of urea-formaldehyde glue can not exceed 13 seconds (being coated with 4 glasss).
Titanium white paper is before dipping urea-formaldehyde glue, and paper tape, by back of the body paint roller, is first coated urea-formaldehyde glue at the lower surface of titanium white paper, allows urea-formaldehyde glue permeate into from the lower surface of titanium white paper, and the air containing in titanium white paper fiber is driven out of from the upper surface of paper.In addition, increase as wide as possible the contact area of back of the body paint roller and paper tape, titanium white paper is infiltrated more abundant.Between back of the body paint roller and dipping tank, be provided with a time-delay roller, for increasing the time of urea-formaldehyde glue infiltration.
After back of the body paint roller, titanium white paper dipping urea-formaldehyde glue: paper tape is drawn in the dipping tank that fills urea-formaldehyde glue, and paper tape is immersed in urea-formaldehyde glue completely, and dip parameters sees the following form 1.After dipping tank, paper tape, through metering roll, by regulating the size in metering roll gap, regulates the spread of titanium white paper.
After this step, in the fiber of titanium white paper, be full of urea-formaldehyde glue.
Table 1 dip parameters
| S roller | Once floating | Extruded roller | Paper injection chain | Upper coating | Lower coating | Secondary is floating | Draw paper-cut |
| 1.3 | 1.00 | 0.99 | 1.00 | 0.50 | 0.30 | 0.70 | 1.00 |
4. dry for the first time:
After gluing completes for the first time, titanium white paper enters first paragraph baking oven district (the baking oven composition in He Er district of You Yi district, the temperature of baking oven and air-heater frequency are in table 2) and is dried.After dry, the fugitive constituent that titanium white paper contains 10-15%.
5. gluing for the second time:
The glue of gluing for the second time: employing be modified cyanurotriamide glue, be under 92 DEG C, weak basic condition, to carry out sudden reaction with melamine and formaldehyde, modifier etc. to make.Modified cyanurotriamide glue can be realized high temperature demoulding, at 200 DEG C, can realize rapid curing in 30 seconds.And common melamine glue must cooling rear demoulding, if demoulding there will be crackle under high temperature.
Coat respectively modified cyanurotriamide glue by anilox roll at lower surface, the upper surface of titanium white paper.Upper surface net painting modification melamine glue first to after the following table veil of titanium white paper correction property melamine glue, then to titanium white paper.
After this step, the lower surface of titanium white paper, upper surface are all covered with one deck modified cyanurotriamide glue-line.
6. dry for the second time:
After gluing completes for the second time, titanium white paper enters second segment baking oven district (baking oven by San Zhi 6th district forms, and the temperature of baking oven and air-heater frequency are in table 2) and is dried.After dry, the fugitive constituent that titanium white paper contains 5.5-6.0%.
The parameters of table 2 baking oven
| One district | 2nd district | 3rd district | 4th district | 5th district | 6th district | |
| Oven temperature (DEG C) | 130 | 130 | 130 | 130 | 125 | 125 |
| Air-heater frequency (Hz) | 30 | 30 | 30 | 30 | 30 | 30 |
6. cooling and cut:
From baking oven out, finally by supercooling with cut and obtain bond paper, its spread is 120%-130%.
Adopt the covering power of the bond paper of production method production of the present invention can reach the level of the high quantitatively bond paper that (85g) titanium white paper is made, therefore, the bond paper of producing with said method has overcome the poor problem of bond paper covering power that low quantitative titanium white paper is made, meanwhile, use low quantitative titanium white paper to produce bond paper and also greatly reduce production cost.
In dipping process, be coated with this technique of titanium dioxide, both can be used for decorative high-pressure pressing plate bond paper and produced, also can be used for short period low pressure decorative paper and produce.
Should be understood that, application of the present invention is not limited to above-mentioned giving an example, and for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
